How about a simple test to see if the rings are due to thin film interference? I doubt it, as that implies very high quality manufacturing, with precise rings of very uniform and varying thicknesses, but a test is easy. Try using monochromatic light. Even just the green (or red) 'charging' LED light on a phone/laptop charger should change the pattern if ...

Judging by the smoothness and regularity of the spectrum, this appears to be simple refraction through the plastic. Thin-film interference would generate a much less regular pattern. In this instance, the plastic disk is acting as a sort of prism. If you want a thin-film interference type of effect, you can look at the disk (from either side, if I recall ...

Have a look at my answer to Slit screen and wave-particle duality because this covers a lot of topics relevant to your question. You're correct that if we imagine the photon as a little ball then if the arms of the interferometer are different lengths the two "halves" of the little ball cannot arrive at the detector at the same time. But this is not how the ...

When one says "photon" one is in the quantum mechanical frame. Quantum mechanics does not follow the rules of classical mechanics if one tries to consider the photon one classical entity, like a bag of energy flowing. The photon is a point like elementary particle in the standard model, it has no extent and when it hits the detector it registers at a ...
